UNITED STATES CHARLES G. SINGELYN, or DETROIT, MICHIGAN;

ELECTRIC AUTOMATIC A IR REGULATION FOR-AUTOMOBILE GAS-ENGINES.

ToaZZ whom it may concern:

' Be it known that I, CrrARLEs G. SINGELYN, a citizen of the United States, residin at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Electric Automatic Air Regulation for Automobile Gas-Engines,

and declare the following to bea full, clear,

I ning-speeds, in gas engines of motor vehicles.

The object is to provide a device that is simple, inexpensive and easily installed and will furnish to the gas engine an additional supply of air for the gas mixture, at the higher running speeds.

A further object is to provide a device as above described, that is automatic of regulation'and will admit an additional supply of airgin volume directly proportional to the flow of current from the generator to the battery.

A further object is to provide a device as above described, that is capable of being so regulated that the admission of additional air supply to the gas mixture will automatically be proportioned to the flow of current from the generatoriand such admission can be set to begin, by regulation of the device, when any predetermined strength of current flow has been reached, such current flow bearing a direct ratio to engine running speed.

In the drawings:

Figure'l 1s a diagrammatic view of a gasolene' engine of conventional type showing myqdeviceas connected to the intake manifold, illustrating the electrical wiring of the same. 0

Fig. 2is a side elevation ofthedevice. Fig.3 is a longi" inal'sectlonal view. Similar numeral's ifrefer to similar parts throughout the drawings.

Referringgrnere particularly to the drawings, in Fig. 1, 1 represents the intake mamfold. ina'ny form of gas engine designed for use inself propelled vehicles, 2 is the device assembly attached thereto, preferably by having the plunger guide 5, inserted there- Specification of Letters Patent.

in by being screwed into a threaded aperture in the manifold. The manner of attachment, or place on the intake pipe where 1t is attached, is immaterial so an open passageway is provided from the inlet holes 6,

except when closed by the position of the plunger, tothe interior of the intake pipe. The plunger is referred to in the drawings as indicated by Fig. 7. The device will be located as shown, in the direct charging line from the generator 3. The circuit is completed through the ammeter A. to the storage battery 4, and back to the generator 3.

Fig. 2, a side elevation ofthe device,-

shows the plunger guide 5 adapted tube inserted into the intake pipe 1, by being threaded so as to screw into a threaded aperture provided in the intake pipe. The

plunger guide 5 is provided with inlet holes 6, in such number as is desired, for example five or six to the inch, or lesser or greater number per inch, as is thought desirable. The plunger 7 is preferably ofsoft iron, and is maintained in the plunger guide in normal position covering'the inlet holes, by means of a tension spring 8, one end of which is attached to the plunger guide 5, and the other end'to the plunger 7 in manner asillustrated, or other convenient fashion. Numeral 9 designates a suckingcoil or solenoid. The relative vertical position of the magnetic solenoid with the plunger determines the extent of vertical movement of The deviceis located inthe charging line from the generator. At the lower speeds, and by lower speeds may be taken to mean below fifteen miles per hour, the amount of current passing through the magnetic solenoid from the generator will not be suflicient to draw the plunger down sufliciently to uncover the inlet holes in the plunger guide. As the speed of'the motor increases however, and more current issues from the generator the current passing through the magnetic solenoid increases and the plunger is withdrawn and the first of the air inlet '35 higher speeds, eliminate the heaving running holes are uncovered and air entering there-- .ject desired.

' The purpose is apparent. At the higher speeds a lighter mixture is desirable, and

by the 'use of the device herein provided with its consequent increase of current through the magnetic solenoid, withdrawal of plunger admitting of additional volume of air to the intake pipe upon increase in speed of the motor is automatically provided for. It will be seen that the plunger may be made to uncover at alower or higher speed by lowering or raising the magnetic solenoid with reference to the plunger. When thus arranged it will automatically begin to un cover at the reaching of the pre-determined speed. A tension spring for maintaining the normal position of the plunger of any desired degree of tension may of course be provided, likewise mechanical means for setting degree of tension. Not only will there be by that means an increase in mileage, by Virtue of using the lighter mixture, which is possible at the higher speeds, but the reduction of the mixture will, at such and reduce the formation of the carbon in the cylinders.

It is apparent that the magnetic solenoid might be placed in series with the low tension side of the magneto instead of in the charging line from the generator and ,the operation of the device would be the fitted therein and provided with an air passageway thereto, air inlet holes through the plunger guide leading from the inner air passageway to the atmosphere, a tension spring holding said plunger in normal position in the plunger guide so as to cover the air inlet holes, said solenoid bearing such relative position to the plunger that the plunger will be withdrawn in the plunger guide upon sufficient increase of current through the solenoid, such withdrawal being in direct ratio to the current flow from the generator.

2. In a gas engine for motor vehicles, the combination of a plunger guide fitted with a plunger, said plunger guide being fitted to the intake pipe, such intake pipe, an air passageway in said plunger guide communicating by means of air inlet holes with the atmosphere, a tension. spring holding said plunger in the plunger guide covering said air inlet holes, a generator, a solenoid in the electrical circuit located in the charging line from such generator and so disposed with reference to the plunger it encircles that a determined strength of current therethrough acts upon the plunger drawing it down into the solenoid and uncovering the air inletholes in the plunger guide, in direct ratio to said flow of current through the solenoid from the generator.

I 3. In a gas engine for motor vehicles, a generator, a magnetic solenoid in the electrical circuit located in the charging line from such generator, a plunger within said solenoid, an intake manifold, a plunger guide fitted to the intake manifold and provided with an interior air passageway thereto, such passageway being adapted to receive the plunger and being provided with air inlet openings leading to the atmosphere normally closed by such plunger, withdrawal of said plunger from the plunger guide by increase in flow of current from the generator through the solenoid operating to uncover the air inlet opening to the interior passageway in the plunger guide.

4. In a gas engine for motor vehicles, in combination with a generator, a magnetic solenoid in the electrical circuit located in the charging line thereof, a plunger within said solenoid, a plunger guide fitted to the intake manifold and provided with an air passageway thereto, said intake manifold, such passageway being provided with atmospheric openings, the withdrawal of said plunger from the plunger guide by increase in flow of current from the generator through the solenoid opening to uncover atmospheric openings to the air passageway in the plunger guide. In testimony whereof, I sign this specification.
